IMPROVEMENT IN COMPOSITIONS FOR AND CONSTRUCTION 0F PICKLINGNATS.

*Specification forming part of Letters Patent No. 217,205, dated July 8, 1879; application filed June 4, 1879.

To all ultom it may concern:

Be it known that I, JOHANN HERMANN DREYER, ot" New York,in the county and State of New York, have invented a new and Improved Composition for and Construction of -Pickling-Vats, of which the following is a specication.

Figure lis a plan or top view of lnyimproved pickling-vat, and Fig.2 a vertical central section of the same.

Similar letters of reference indicate corresponding parts in all the iigures.

This invention relates to a new construction ot vat used for picklin g meats preparatory to smoking them. Heretofore such meats have been usually pickled incasks or barrels, wherein they were retained for a prper length ot time, and from which they weresubsequentlyremoved to be smoked; but experience has shown that Ithe ordinary casks or barrels do not constitute suficientnoncouductorsofheattoproperlypreserve the meats in the warmer season,inasmuch as the meats to be smoked are not pickled to the same extent as those which are to be brought into market in the pickled condition only. In other words, the preparation in which the meat is contained does not suice to prevent decomposition during the hot season. My invention seeks to provide a vat in which the meat will be held and preserved free from danger of decomposition even during the heated season, and by the use of which large sums of money which are now expended for ice and other preservativeswill beeconomized,though,0f course, ice may also be used around my improved vat. The vat may also be used for other purposes than those of containing pickled meats-for example, in breweries, ice-houses, &c.

My invention consists, rst, in a new composition for the blocks of which the vat is constructed; and, second, in the new construction of vat, which is provided with locking-pieces at the top, and protected against the injurious eliects of acids in all respects, as hereinafter more fully described.

Thevat shown in the drawings is built up of series of bricks or blocks, a a, which are Where series of vats are to he used in the same structure, I prefer to make them contiguous, so that the wall of one will also be that ofthe other-in other words, so that the upright walls will be partitions between two adjoining vats placed in one row.

The blocks a are constructed as follows: I mix about one part ot' Portland cement with about three parts of coal-ashes and about one part of mineral woo ese ingredients are put toge er w1 e assistance ot' sutcient water to render them plastic, and are then laid o l ry and set in a suitable mold to produce the required blocks. The blocks thus made are non-conductors ot' heat, better, in fact, than any known to me, and therefore particularly adapted to be used in a vat of the kind described. Instead ofthe mineral wool, which is the principal non-conductor, equivalent nonconducting material may be used in the blocks,

such as oak-bark or sawdust repared with li uid lass lint the mineral wood is preferred, vingt t o 1 s superior non-conducting property, and owing to its neness of structure, which enables it to enter more freely into all parts of the blocks, also because it is absolutely fireproof.

Having built up the tank from these blocks, as stated, I next line the inner as well as the outer side of the tank with a coat of cement, b b, which will prevent the escape of acids or piekling-liquids from the tank through the interstces between the blocks. In to two opposite upright walls of thc tank I anchor T-bolts d which extend through the upper ends of said walls, as indicated in Fig. 2, aud serve to hold grooved rods c, of wood, that are fastened down upon the tank by means of nuts f, screwed upon the upper ends of the T'holts, as shown These nuts are sunk into the grooved wooden,

A bars, as shown at the left-h and side of Fig. 2, and

are afterward covered with cement, as shown at g at the right-hand side of Fig. 2, so that the acids contained in the pickling-liquids cannot aiect the iron-work. Infact, by the construction shown all the iron-work is entirely. out of reach of the liquids.

laid or placed to constitute the bottom and ,5 The grooved rods chave their grooves at the the upright walls of the vat, in manner shown. l lower sides, as shown, so that they will serve sired.

I claim- 1. The composition for the block a, the same being made of Portland cement, coal-ashes,

and mineral Woo1,substautiallyin the proportions specicd.

2. The vat or tank, constructed of composition blocks a, and lined on the inner and outer sides with cement, substantially as specified.

3. The combination, in a tank built up of vcomposition blocks a., ofthe T-bolts d, grooved rods c, and sunk nuts f, substantially as herein shown and described.
